For this patch i wanted to recreate a deep house bass patch that had a quick attack and release times. For this i have inputted the midi above and i have set the tempo to 120 bpm. For the synth i have used Logic’s stock EFM 1 to achieve this.
Ive wanted to keep the patch relatively simple and so i have set the patch to have only 1 harmonic as to not over saturate the sound and not deviate from the initial bass sound and not bring in too much harmonic content.
Ive also maxed out the sub osc level to bring in more sine wave sub bass to give the sound more lower sub bass frequency and to provide a fuller and rounder sound.Ive also set the stereo detune to max as to provide a more discordant and unison sound to provide more harmonic frequencies from the initial simple sound.
As for the envelope for the patch, i have set the attack to a fast setting to emulate the quick bass shots that is prominent in deep house. As for the decay and sustain, i have set them relatively high since most of the dynamics and harmonics come from the short plucky sound. As for the release ive set it relatively low to so that it doesn’t cut off too quickly or let it ring out for too long.
The modulation amount is controlled with the FM Depth knob and the ADSR envelope at the top. I have automated this to allow more FM modulation to pass as the midi sequence plays. The modulation envelope is set so that as more of the carrier signal is introduced, the release increases to change from the plucky sound into a longer release sounding bass shot. By turning the devolve the sound to a harsh, harmonically rich sound
